本发明为了达到上述效果而具备的主要构成要素包括下列单元：框架，位于驾驶座的下部且其前方具有开口；回旋件，通过结合件连接到上述框架的开口并可以侧向旋转；门架（mast)的倾斜角调节单元，位于上述回旋件的一侧并以上述回旋件的旋转轴作为基准进行回旋运动，连接到倾斜杆（tilt rod);货叉（fork)的升降卨度调节单元，位于上述[eJ旋 The present invention in order to achieve these results and have the main components include the following elements: a frame, lower part of the driver's seat and its front has an opening; swing member, by binding member is connected to the opening of the frame and can be lateral rotation; mast ( mast) tilt angle adjustment means located on one side of the swing member and a rotation axis of the swing member as a reference swing movement, is connected to the tilt lever (tilt rod); fork (fork) lift 卨 adjustment unit, located at the [eJ spin
件的后方，以垂直于上述回旋件的旋转轴的轴作为基准进行回旋运动，连 Rear member, perpendicular to the axis of rotation of the revolving shaft member as a reference cyclotron motion, even
接到提升杆（lift rod);以及调整杆，连接到上述升降高度调节单元并可以调节门架（mast)的倾斜角与货叉（fork)的升降高度。 Receiving the lift lever (lift rod); and the adjusting lever, connected to the lifting unit and can adjust the height adjustment mast (mast) with the inclination angle of the fork (fork) lifting height.
如图l所示， 一般叉车在其正面以多段型Sliad方式垂直安装了门架120，上述门架120上安装了可以承载并举起货物104的货叉106，上述货叉106由起升油缸驱动，上述门架120的后尾则安装了可以调整倾斜角度并给予支持的倾斜油缸108，上述起升油缸与倾斜油缸108则由可以使控制阀V的滑阀（Spool)进行升降运动的提升杆L与倾斜杆T驱动。 Shown in Figure l, general truck on its front with multi-stage type Sliad Vertical installation of door frame 120, installed above the door frame and can carry cargo lift forks 106 104 120, 106 by the above-mentioned fork lift cylinder to drive lift lever, after the end of the door frame 120 is installed you can adjust the tilt angle and support the tilt cylinder 108, said lifting cylinders and tilt cylinder 108 by the control valve V can slide valve (Spool) is vertically moved in L and T tilt rod drive.
上述提升杆L与倾斜杆T分别由独立的两个驱动杆120130驱动，上述两个驱动杆分别由操作人员进行调整，因此需要分别调整起升操纵杆120与倾斜操纵杆130，增加了工作的复杂性。 Said lift lever and the tilt lever L T driven by two independent drive rod 120,130, respectively, the two drive rods is adjusted by the operator, and therefore need to separately adjust the lifting lever 120 and tilt lever 130, increasing the work Complexity.
例如，为了在举升货叉106的同时把门架102倾斜到对地面成90°以上的角度，需要同时拉起起升操纵杆120与倾斜操纵杆130;而在其它作业中，需要在举升货叉106的同时拉起门架102并使门架102与地面的角度低于90° ，此时则需要对起升操纵杆120做出拉起动作而对倾斜操纵杆130则做出前推的动作。 For example, in order to lift the fork 106 while the door frame 102 is inclined to the ground at 90 ° angle above, we need to pull the lifting lever 120 and tilt lever 130; in other operations, the need to lift fork while pulling up the mast 102 106 102 and the angle of the door frame and the ground is less than 90 °, this time you will need to lift the lever 120 to make a pull action of the joystick 130 to make the front push action.
以上述方式同时操作两个操作杆时需要运用双手，因此在操作起升操纵杆120与倾斜操纵杆130的过程中无法操作驾驶盘或喇叭（horn)。 We need to use both hands in the manner described above simultaneous operation of two operating lever, so the process of lifting the operating lever 120 and tilt lever 130 can not operate the steering wheel or horn (horn).
图2的标记140是泵控制开关，可以检测出起升操纵杆120被拉起到最大幅度并增加液压泵的输出。 Mark 140 of FIG. 2 is a pump control switch that can detect lifting the lever 120 is pulled and played the most significant increase in the pump output.
操作人员为了熟练地操作起升操纵杆与倾斜操纵杆而需要接受大量的训练，还需要花费很多精力防止操作人员因为一时疏忽而造成事故。 The operator to manipulate the joystick and the joystick lifting and need a lot of training, but also takes a lot of effort to prevent operator accidents caused due to negligence.
为了解决上述问题，虽然可以如美国专利公报第6,273,669号"可以选择性地控制叉车的倾斜与起升动作的单杆（Single Lever With ButtonFor Selective Controlling Either Tilt Or Lift Of A ForkliftMechanism)"中所揭示利用单杆控制两个阀，但上述美国专利是通过电子控制器的信号来检测出杆的旋转量或位置并根据上述信号对控制阀进行控制，由于叉车需要在恶劣的环境中工作而使检测传感器常常发生故障，而且由于无法适用于已设计完毕或制作完毕的叉车而无法防止经济上的损失。 To solve the problem, although as U.S. Patent No. 6,273,669, "can selectively control the tilt and lift truck movements a single shot (Single Lever With ButtonFor Selective Controlling Either Tilt Or Lift Of A ForkliftMechanism)" disclosed use Single-lever control two valves, but the aforementioned U.S. Patent by the signal of the electronic controller detects the rotation amount or location of the bar and on the basis of the signal control valve is controlled, since the truck need to work in harsh environments leaving detection sensor often fails, and inability to apply has been designed to manufacture finished or finished truck can not prevent economic losses.
